vital functions
Body's core operations
The vital functions are the basic physiological processes necessary to sustain life—breathing, heartbeat, circulation, and similar activities.
Medical contexts distinguish vital functions from other bodily processes: The patient's vital functions remained stable during surgery.
By extension, vital functions can refer to any essential operations: The backup generator maintains the building's vital functions during outages.
